Application Information

The OPA177 is unity-gain stable, making this device easy to use and free from oscillations in the widest range of circuitry. Applications with noisy or high-impedance power-supply lines can require decoupling capacitors close to the device pins. In most cases, 0.1‑µF ceramic capacitors are adequate.

The OPA177 has very low offset voltage and drift. To achieve highest performance, optimize circuit layout and mechanical conditions. Offset voltage and drift degrades because of small thermoelectric potentials at the op-amp inputs. Connections of dissimilar metals generate thermal potential that can degrade the ultimate performance of the OPA177. To cancel these thermal potentials, make sure the thermal potentials are equal in both input pins.

  1. Keep connections made to the two input pins close together.
  2. Locate heat sources as far as possible from the critical input circuitry.
  3. Shield the op amp and input circuitry from air currents, such as cooling fans.
